Is Qt5Network.dll safe?
No engine detections, a verified CD PROJEKT signature, broad historical prevalence, and five matching publisher precedents strongly support this Qt networking library.
None of 74 antivirus engines flagged this DLL, and its CD PROJEKT S.A. signature verifies correctly. It is widely observed, has five publisher-matched precedents with favorable findings, and produced no malicious sandbox verdict or dropped payloads.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
None of 74 antivirus engines flagged this DLL, and its CD PROJEKT S.A. signature verifies correctly. It is widely observed, has five publisher-matched precedents with favorable findings, and produced no malicious sandbox verdict or dropped payloads.
The antivirus result is uniformly favorable: 0 of 74 engines reported a malicious or suspicious finding, including no tier-1 detections. The DLL carries a verified CD PROJEKT S.A. signature, with no detected mismatch between its claimed brand and signer. It has been submitted 426 times by 383 sources and has existed in the dataset for 431 days, which supports an established software component. Five similar files matched by the same verified signer previously received favorable findings. One sandbox mapped T1560, but it found no malicious verdict, persistence, dropped payload, or network contact. Static analysis also found no packed or high-entropy code section.
What We Detected
None of 74 antivirus engines flagged the DLL, and ten tier-1 engines explicitly reported no detection. The file is signed by CD PROJEKT S.A., the signature verifies correctly, and no brand mismatch was detected. It is also well established, with 426 submissions from 383 sources over 431 days.
Threat Behavior
One completed sandbox run produced no malicious sandbox verdict, persistence indicators, dropped payload hashes, or observed no complete contacted-host reputation result was available-common techniques, but the isolated mapping lacks corroborating malicious activity. Static PE analysis found neither packed code nor suspiciously high-entropy code sections. No complete contacted-host reputation result is available because the host cross-check was not saved.
What To Do Now
The evidence is consistent with a legitimate Qt networking library distributed with CD PROJEKT software. Keep endpoint protection enabled and obtain the DLL through the official application installer or trusted update channel rather than an unrelated download source.
Where this verdict could be wrong3 caveats
- The completed sandbox mapped T1560, an archive-collected-data technique, but it produced no malicious sandbox verdict and was not accompanied by persistence, dropped payloads, or network contacts.
- signing.signerStats.totalSamples=1 provides limited direct signer-history depth, although five signer-matched prior decisions independently support the publisher pattern.
- contactedHosts=null means no complete host-reputation cross-check is available, though the sandbox recorded no contacted domains, IPs, or URLs.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 0/74 antivirus engines reported malicious or suspicious findings.
- Verified digital signature from 'CD PROJEKT S.A.'.
- 383 unique sources and 426 submissions over 431 days.
- 5/5 signer-matched prior files received 'safe' verdicts.
- peAnalysis.highEntropyCode=false and peAnalysis.likelyPacked=false.
- One sandbox mapped MITRE technique T1560 without corroborating malicious activity.
- signing.signerStats.totalSamples=1 limits the depth of direct historical signer statistics.
- contactedHosts=null, so no complete host-reputation cross-check was available.
Use the DLL only as part of an official CD PROJEKT installation or update, and keep endpoint protection enabled. Re-download from the official source if its location or origin is unexpected.

Section entropy & packers
No high-entropy executable section or known packer signature was detected. Data and resource sections can still have high entropy without indicating packed code.
How widely this file has been seen
Widely seen in the wild for a long time. High prior this is legitimate; isolated detections on common-old files are usually false positives.
